Performance Analysis of Solar-Coal Cogeneration System for Wind Power Consumption
During the heating season, the limited peak shaving capacity of CCHP units is blamed as the major cause for the massive abandonment of wind and light in the "Three Norths" area. A mathematical model of key equipments for the solar aided CCHP system is established in this paper. Then a desk...

| description | During the heating season, the limited peak shaving capacity of CCHP units is blamed as the major cause for the massive abandonment of wind and light in the "Three Norths" area. A mathematical model of key equipments for the solar aided CCHP system is established in this paper. Then a desk-top case of a 600MW direct air-cooled CCHP unit with a 100 MW wind farm, 510,000 m2 solar field, and 3-hours storage system is investigated under actual weather conditions and load demands. The simulation results show that, in the heating mode, the lower limit of unit peak shaving can be reduced by 150 MW for wind power consumption so as to promote the integration of large scale wind power into the grid. The annual wind curtailment has dropped from 20 million kW·h by 62.2% to 7 million kW·h, and the wind curtailment rate has dropped from 7.91% to 2.7%. Meanwhile, the annual solar power generation has reached 150 million kW·h, equivalent to a total of 49000 tons of coal saved and 132000 tons of carbon dioxide emissions reduced, which has demonstrated significant environment and economy benefits. |
